“…The introduction of the concept of the "uncertainty of measurement" is a necessary measure to obtain uniform and simplified assessment of the reliability of the evaluation of measuring authenticity, since its definition is based on obtained measurement results, known conditions of the measurement, and the characteristics of the equipment, and not on the unknown actual value of a measured value [6].…”

Abstract. The task of evaluating uncertainty in the measurement of sense in natural language constructions (NLCs) was researched through formalization of the notions of the language image, formalization of artificial cognitive systems (ACSs) and the formalization of units of meaning. The method for measuring the sense of natural language constructions incorporated fuzzy relations of meaning, which ensures that information about the links between lemmas of the text is taken into account, permitting the evaluation of two types of measurement uncertainty of sense characteristics. Using developed applications programs, experiments were conducted to investigate the proposed method to tackle the identification of informative characteristics of text. The experiments resulted in dependencies of parameters being obtained in order to utilise the Pareto distribution law to define relations between lemmas, analysis of which permits the identification of exponents of an average number of connections of the language image as the most informative characteristics of text.

“…As has been demonstrated in the relevant literature [4][5][6][7][8][9][10][11][12][13][14], the basic characteristics of MM include sensitivity, additive errors, multiplicative errors, measurement ranges, and primary and secondary errors (uncertainties) in the MM which in international scientific metrology practice is sometimes known as the Measurand Model. These characteristics are sufficient to establish standards for the accuracy of the MM [11,12].…”

Abstract. This paper proposes a method of determination of the basic metrological characteristics of measurement means (MM) in order to measure the torque of electric motors (EM), such as sensitivity, nominal conversion functions, and additive and multiplicative errors. The nature of change of metrological characteristics was researched using the Measurand Model derived, in the conversion measuring range studied in this paper. Summarised values for additive and multiplicative errors were established for the MM of torque, under the conditions of deviation in terms of the impact value from its nominal value. In addition, the methodology was analysed to enable recalculation of additive and multiplicative errors related to the standard uncertainty of type B. This was undertaken to establish the quality of measurement according to international standards. The research was founded on Measurand Model obtained for multiplicative and additive components in the errors inherent in torque MM.
